Now let’s see what is going to happen if we load the CPU with work. First we will measure the power consumption during WMV-video playback in Windows Media Player 10.

Video playback is hardly a hard task for the system CPU. Therefore, the picture we observe here is very similar to what we saw in idle mode. Energy Efficient AMD processors turn out more efficient than Intel Core 2 Duo, while the “standard” Athlon 64 X2 loses to its brothers as well as to the competitor.

If we load the testbeds with harder tasks, such as gaming applications, for instance, the situation will change:

Energy Efficient Athlon 64 X2 4600+ with the 65W TDP starts to fall behind the Intel Core 2 Duo E6300 processor from the “performance-per-watt” standpoint. Only the 35W Athlon 64 X2 3800+ manages to prove its name (in terms of power consumption). However, its performance is about 10-12% lower than that of the Core 2 Duo E6300 and Athlon 64 X2 4600+.
